If the magnitude of the sum of two vectors is less than the magnitude of either vector, then:

a. the scaler product of the vectors must be negative

b. the scaler product of the vectors must be positive

c. the vectors must be parallel and in opposite directions

d. the vectors must be parallel and in the same direction

e. none of the above.

Are you supposed to pick an answer to go with each of the first two statements? The magnitude of the vector sum of A and B must be in the range between |A| + |B| and |A| - |B| (assuming |A| is larger than of the same as |B|)

(a) through (d) are not true in either case.
